Photoinduced reversible spin-state switching of an Fe III complex assisted by a halogen-bonded supramolecular network

The organization of a molecular FeIII complex embedded in a halogen bonded 2D network is chemically tuned to trigger temperature- and light-induced spin-state switching. We attribute the associated magnetic properties and the unprecedented photoswitching effect to the optimized structural confinement provided by the presence of the supramolecular host framework.Matériaux Moléculaires Ferroelectriques (et Magnétiques
